FLUID-FUEL BURNER;

Application niaremuay 29, 192,4.,` sfriaiiv'laawa To all whom t mayconcern.' n

Be it known that I, THorIAs J. MAJCHRZAK,

a 4citizen of the Unitedr States, residing at Grand Rapids, in thecounty ofk Kent and i Statev of Michigam'have invented 'new and usefulImprovements in kF1uid-li`uel Burners, of which the following is a'specification.

The present inventionvrelates to fluid-fuel burners; and its object isto provide fin such a burner meansA for forcing the flame ina horizontaldirection by an air-draft, to thus heat a surroundingair-heatingelement; and further, to provide in-such a burner iin--`proved specific parts and constructions.

This and any other *objectsv hereinafter appearing are attained by, andthe invention finds preferable embodiment in, the structure hereinafterparticularly described in the bodyof this specification and illustratedby the accompanying drawings, in which Figure 1 is a`vertical sectionalview of a furnace having a fluid-fuel burner applied thereto;

Figure 2 is'a top plan view of the burner, its upper member beingpartially lbroken away;

Figure 3 is a side view of the same, shown partly4 in central verticalsection taken on line 3 3 of Figure 2; and

F'igure 4 is another side view of a portion of thesame, partly sectionedon line 4--4 of Figure 2.

In the construction illustrated by the drawings, the furnace 1 having acasing 2 is equipped with an oil-burner which comprises a base member 3suitably supported, as by the hollow cylinder 4 resting on thegrate-bars 5 of the furnace, which (as in the form shown) may have beenoriginally intended for burning solid fuel. member 3 has a verticallydisposed air-draft passage 6 therethrough, registering with a likepassage 7 through the cylindrlcal .support 4. The burner comprises alsoan upper member 8 forming the upper wall of the upper portion of theair-draft passage 6 and having its under surface 9 inclinedupwardly-outwardly as particularly shown in Figure 3. The burner furthercomprises a feeding pipe 10 for the oil, whose discharge vent 11 islocated below the upper member 8 and adjacent the upper and outer end ofthe passage 6. Oppositely disposed opentop containers or shallow,basinsl 12 are formed in the' upper end ofthe base mem-4 ber 3 and areprovided with drain pipes`13 This baseeirtending upwardly 'vthereintovto .drain the'rv `o1l accumulating 'above the level of their innerends.The upper member 8 has La centrallydi'sposed orice 14 through which (andthrough the, air-dra'ftkkopenings' and 7) the feeding pipe entendsupwardly, then bl'a-nchin" Iat`1'5, 15 vand,'extending down. wardly tyrough holes 16,116 in the upper member to" their discharge' vents. Thebase member 3 has oppositelyfdisposed upwardly extending flanges 17, 18between the basins' 12 and provided'with shallow airdraft ldepressions:19 through which any gas' which collectjisexpelled,vby the draft,between the upperand lower members 8 and 3, and is consumed by theflames of the burning oil. These flanges have wing portions 2() at theirends, the discharge vents 11 of the branches 15 of the feeding pipebeing located between adjacent portions 20 of the two anges.

It will be seen that the flames (indicated -at 21) from the burning oilin the shallow basins 12 are driven outwardly in a horizontal directionby the air passing upwardly through the passage 6 and betweenthe uppermember 8 and the base member 3, and are thus driven against theair-heating element 22 forming the combustion chamber of the furnace,and ,thus thoroughly and quickly heats the same, so that the airsurrounding the furnace is heated in like manner.

It will also be seen that the parts comprised in said burner areparticularly well adapted to effect the general purposes of myinvention. A pan or plate 23 may rest on the grate bars 5 and be coveredwith heatinsulating material 24, as ashes or the like, to confine theheat from passing. downwardly. between the grate bars.

The invention being intended to be pointed out in the claims, is not tobe limitedk to or by details of construction of the particularembodiment thereof illustrated by the drawings or hereinbeforedescribed.

I claim:

l. A burner having a vertically disposed air-draft passage therethroughwith an up- Wardly-outwardly inclined upper portion, and having' afluid-fuel feeding pipe with a discharge vent below and adjacent theupper wall of the upper-outer end of said passage.

2. In a burner: a base member having a vertically disposed air-draftpassage therethrough; an upper member having an upsok wardly outwjardlyi'ilined 'u'nder surface and forming" the upper wall of rthe upperrportion of said passage; a fluid-fuel feeding v pipe having adischar'gefvenr) be1ow" 'sai 2 upper member and adjacent the.upperfouter of said passage. p 3.
